防止电机反馈试验失控的调节方法及参数设计

Regulating Method and Parameters Design for Preventing the Loss of Control in Traction Motor Feedback Tests

根据电压和功率平衡的关系分析了牵引电动机反馈试验中的电流或电压失控现象 ,发现失控的原因是各电机磁场特性的差异所致 ,得到了不出现失控的磁场限制条件 ,提出采用调磁的方法来消除失控现象。对调磁装置及其技术参数进行了设计 ,使之能满足所有试验的调节要求。

The loss of control of current or voltage in traction motor feedback tests is analyzed based on voltage balance and power balance, and the restrictive conditions of non loss of control is obtained. Since the loss of control is caused by the difference in magnetic field characteristics of motors, a method by regulating the magnetic field is put forward to eliminate the phenomenon of loss of control. The magnetic field regulating device and technical parameters are designed to meet the regulating requirements for all the motor tests.
